Opioid use and infectious diseases are intertwined epidemics. Despite the fact that the United States is more than two decades into the opioid crisis, public health systems have not sufficiently addressed the morbidity and mortality of drug use coupled with infectious diseases. A NASEM consensus will conduct a study to determine how to better integrate services for opioid use disorder and infectious diseases. The committee will identify programs that are integrating services, draw out best practices and barriers to integration, and issue recommendations to address the dual epidemics of infectious disease and opioid use disorder.
